According to the documentation for Laravel Lumen, it's possible to make use of the CSRF helper function to generate a CSRF token. However, when I go ahead and use the csrf_field function or the csrf_token function, I am presented with an error message:
Call to undefined function csrf_field()
and
Call to undefined function csrf_token()
respectively.
It would appear as though some people are saying CSRF protection is not a part of Lumen, but since it's listed by the documentation I'd assume it is.
It's fairly possible I've overlooked something rather simple. Do I somehow need to tell Lumen that I'd like to use this helper specifically? Anyhow, any pointers in the right direction would be very much appreciated!
Lumen doesn't have these helpers. You can check it by yourself by looking into the source code. So, you'll need to insert token manually:
<input type="hidden" name="_token" value="{{ app('session')->token() }}">
